ALTERNATlNG-CURRENT GENERATOR.

SPECIFICATION running part of Letters Patent No. 491,811, dated February14, 1893. Application filed July 8,1892. Serial No. 489,440. (No model.)Patented in France December 11, 1891, N0. 217,998-

To aZZ whom, it may concern:

Be it known that I, OOTAVE PATIN, a citi-- zen of the Republic ofFrance, and a resident of Paris, have invented a certain new and usefulImprovement in Alternating Current Electric Machines, of which thefollowing is a full, clear, and exact description.

The invention has been patented in France under date of December 11,1891, No. 217,998.

My invention is an alternate current electrical machine and it includessuch a construction and arrangement of the main parts, the armature andmagnets, by which one of said parts surrounds and overhangs the other,the latter being adapted to be withdrawn from the overhanging part bysuitable devices provided for the purpose.

My machine is constructed with the view of placing it directly 011 theshaft of the engine in the place of the fly wheel. It may be arrangedhorizontally on a vertical axis, as on a turbine wheel if desired.

In the accompanying drawingsz Figure 1, is a front View of the machineas set up. Fig. 2, is a vertical section. Fig. 3, is a plan view. Fig.4, is a side view of the revolving armature. Fig. 5, is a verticalsection of the same. Fig. 6, a side view partly in section of one of themagnet heads. Fig. '7, is a vertical section of the same. Figs. 8 and 9are similar views of the opposite head. Fig. 10, is a plan view of oneof the magnet spool holders. Fig. 11, is a side view of the same. Fig.12, a plan view of a section of the magnet enlarged. Fig. 13, a sideView of the magnet; with a number of spools in place. Figs. 14, 15,16,17, and 18 are views of modified forms of armatures. Fig. 19representsaplan and a side view of a modified form of magnet. Fig. 20,is a modified form of machine showing the application of some of thearmatures shown in the modified views 14 to 18. Fig. 21, is a sidesectional view of Fig. 20.

The base 1 is provided with a tubular proj ection or sleeve 2, upon theend of which the stationary magnet is placed. This is composed of thecrown or head 3,fiXed to the tube by its central hub, and having arms,Fig. 6, and a second head, Figs. 2, 8 and 9, secured to the first bybolts passing through the open ings 2, this latter crown being withoutarms. Between the crowns are interposed a series of plates or bars 18,in the form of segments of washers. These form the magnetic core of themagnet and with the crowns, form a drum like body, over which andtransversely thereof are fixed the spools 14, consisting of therectangular shaped open frames with rounded corners and the wire woundabout the same. The frames are secured to the heads by the screws 16.The frame has a rib 25, which serves to hold the wire in place. Theframe has an interposed packing I, at one part to prevent induction. Thespools are independent and are connected in any suitable manner.

The revolving armature 4, on the shaft 13 is in the form of a ring orshell, having a flange which overhangs the magnet and is provided withinwardly extending teeth, :13, forming poles which are wound in anysuitable manner, and are alternately positive and negative.

In order that the magnet may be withdrawn from the overhanging armature,the spur wheel 8, is operated and through the pinions 11 and 12, on eachside, and the hollow nuts to at connected therewith, operate on thescrew rods 6, 7 and draw them through the ears 30, 31, and thus withdrawthe magnet to the arms of whose crown 3, the screws are connected. Whenthe magnet is thus withdrawn it may be readily repaired and attended to,

and by unscrewing the screw rods 6, and 7,.

the magnet may be turned if desired to bring any portion of it into theproper position.

In Fig. 14, is shown a form of armature in which there is an interiorpart 4 and an outer part 4, both parts turning with each other. Theouter part has a series of inwardly projecting teeth, while the innerpart has its spools projecting outward. The space between is adapted toreceive the spools of the stationary magnet, as shown in Fig. 21. Theconstruction of Fig. 14, includes two shells for supporting the spools,whereas in Figs. 15, 17, 18 and 21, a single shell answers this purpose.The arrangement is such that the poles in each series are alternativelypositive and negative, the poles of unlike sign being opposite eachother. The spools of the magnets are fixed to the metal crown D, Figs.19-21.

As in Figs. 16 and 17, I may use in connec* tion with a series of spoolsproperly wound, a series of unwound short projections E,

E, which serve to become saturated with the induced current. In allthese forms, the one part overhangs or incloses the other and isseparable therefrom, by withdrawing one part.

The machine can be double as in Fig. 18, if desired. The outer parts arewithdrawn in this form, when it is desired to separate the machineparts.

I claim:

1. The combination in an electric machine of the two crowns arranged ata distance from each other and connected by bolts 2, the interposedplates 18 arranged parallel with the heads, and the spools consisting ofthe rectangular open frames extending transversely of the heads andacross the intervening plates, said frames being secured to the headsand having rounded ends to receive the wire wound thereon, substantiallyas described.

In combination the magnet, the tubular support therefor, the shaftextending concentric with said support, the armature ring carried by thesaid shaft and having a flange extending from its radial supporting armslaterally to one side and over the magnet, and means for withdrawing themagnet from the armature, substantially as described.

3. In combination the standard having a tubular projection on one side,the magnet supported on the outside of and at the end of saidprojection, the shaft 13 having an extension at the end of the saidtubular projection, the armature ring supported on the said shaftextension and having a forwardly projecting flange over the magnet ring,the means at the end of the tubular support for retracting the magnetalong the tubular support and the connections therefrom to the magnetextending alongside the said tubular support, substantially asdescribed.

4. In combination, the magnet, the ring armature overhanging the same,the internal teeth on said overhanging portion, and the second series ofteeth carried by the armature and projectingoutwardly within the magnet,both of said series of teeth being radially arranged substantially asdescribed.

5. In combination the magnet, and the ring armature having the series ofspools formed about projecting teeth and the series of unwoundprojections opposite said spools, substantially as described.

In testimony whereof I have-signed this specification in the presence oftwo subscribing witnesses.

OOTAVE PATIN.
